DISK-STACKING DEVICE.

\ Specification of Letters Patent. Patented Se t 20 1921 Applicationfiled November 8, 1920. Serial No. 422,532.

' To all whom it may concern Be it known that I, WILLIAM E. Moons, acitizen of the United States, and residing at Detroit, in the county ofWayne and State of Michigan, have invented a new and ImprovedDisk-Stacking Device, of which the following is a specification.

This invention relates to means for stacking the sheet iron disks usedto make up the cores of the armatures for electric motors andgenerators, that is, to so arrange them co-axially that the key-ways orfeathers by means of which they are positioned on the shafts are alined;and the object of this invention is to provide an automatic shaker withwhich the stacking pins shown in the Collins Patent Number 1,343,351,dated June 15, 1920, may cooperate.

This invention is particularly pointed out in the following claims andillustrated in the accompanying drawing, in which Figure 1 is a plan ofthis improved stacking with the helical shoulders 3 of the stacking pin4 which guide the feathers 1 down to the longitudinal groove 5 in thepin. It has been found that the simple construction shown in Figs. 1 and2 of the drawing en ables theworlnnan to assemble many times the numberof sets of disks that he can by hand.

Mounted on the base 6 is a pedestal 7 within which is an upright shaft8, indicated in dotted lines in Fig. 2. The upper face of the pedestalis formed with a groove with inclined sides, and into this grooveextends the transverse rib 9 on a collar 10. Secured to this collar 10or integral with it is a disk 12 having an arm 1.3 which carries a pin14 in its outer end extending across a slot 15. A base 16 has twoupright posts 17 which support bearings 18 for a crank-shaft 19, onwhich a driving pulley 20 of any desired character is mounted. A crank22 is secured to one end of this shaft and has a crank pin 23 of wellknown construction. A connecting rod 24 has a vertical pin 25 at itscrankpin end and a horizontal pin 26 at the opposite end. A' smallsleeve 27 receives the crank-pin 23 and has a lip 28 provided with ahole to receive the pin 25. The small plate 29 extends into the slot 15in the arm 13 and receives the pin 26 on the connecting'rod.

Rotation of the crank-shaft 22 will therefore cause the arm 13 to swingback and forth and the connections between this arm, the connecting rodand the crank pin permit this movement without binding of the parts. Ateach reciprocation of the arm 13, the disk 12 and the hub 32 thereon iscaused to move up and down by reason of the inclined sides of the grooveand of the transverse rib 9. Any other desired means may be employed tocause this arm 13 to swing back and forth so long as said means permitsthe up-anddown movement of this arm at the same time.

The lower ends 34 of the stacking pins 4 are of such size that they fitthe central hole in the top of the hub 32 on the oscillating member 12,the collars 35 of the pins being provided with notches to receive thesmall pin 36 extending upward from said hub. This stacking device isconstantly in motion and the disks in predetermined numbers for eachcore and the pins therefor are brought to the machine, the lower end ofeach pin being dropped into the hole in the top of the hub 32 and turneduntil the notch in its collar 35 alines with the small pin 36. Theoperator then takes up a hand full of these core-disks and places themover the top end of the stacking pin. The vertical and oscillatingmovements of the pin causes the core-,

disks to aline themselves as fast as they can be placed over the end ofthe pin. When estal having a transverse groove across its 5 top and saidcollar havlng a rib extending downwardly into said groove, a hub on thecollar having a central hole adapted to receive a stacking pin, andmeans to turn the collar back and forth on avertical axis.

2. In a stackin device for the disks of armature cores, t e combinationof a pod-- estal and a collar rotatable thereon, said pedestal having atransverse groove across its top and said collar having a rib extendingdownwardly into said groove, a hub on the collar from said arm to saidcrank pin whereby rotation of the shaft causes voscillation of thecollar.

3. In a stacking device for the disks of armature cores, the combinationof a stackin pin having a longitudinal groove and he ical shouldersextending from the "groove, to a meeting place between them on theopposite side of the pin, means to support the pin in avertical-position, and means to cause the pin to simultaneously turnback and forth and to move up and down.

4. In a stacking device for the disks of armature cores, the combinationof a stacking pin having a longitudinal groove, a hub having a centralvertical socket to receive the lower end of the stacking in, means tocause the hub to turn back an forth on the axis of said pin, and meansto cause the hub to move up and down.

5. In a stacking device for the disks of armature cores, thecombination. of a stacking pin having a longitudinal groove, and meansrotating back and forth on the axis of the pin provided with a socket toreceive the lower end of said pin.
